[0023] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0024] like Figures 1-6 As shown, the present invention provides an auxiliary device for performance detection, comprising: a support base 1, a bearing assembly 2 and at least one working condition simulation device;

[0025] The support base 1 is used to connect with the test machine 7; specifically, the test machine 7 can be selected but not limited to any equipment used in the prior art to detect the performance of the object to be tested, such as detecting the high and low temperature resistance, electrical conductivity, service life, etc. of a certain produced part or material. Its specific structure, test method, working principle, etc. are not described here in detail. The key to the present invention is how to add an auxiliary device for performance testing to simulate the object to be tested into any one or more specific working conditions during use, such as compression, bending, etc., to detect its performance under use and pressure, so that the performance test results are more in line with its use state and more in line with actual application. For example, Figure 6 As shown, a test machine tool of the present invention is provided, but not limited thereto, comprising: a test table 701; a track 702, a test box 703 and a test position 706 arranged on the test table; preferably, the auxiliary device of the present invention is arranged on the test position 706, and slides into the test box 703 via the track 702 to complete the performance test. Preferably, as Figure 5 As shown, the test platform 701 includes two support platforms; the test box 703 can be optionally but not limited to a high and low temperature control box, which is used to provide high and low temperatures to achieve performance testing at different temperatures. More preferably, two drive rails 702 are provided parallel between the upper end surfaces of the two support platforms to provide driving force, and a test box 703 is provided above the drive rails 702 to provide test temperature. More preferably, the test machine 7 also includes an arch 704 to support other devices. More specifically, as Figure 1 and Figure 2 As shown, the support base 1, which can be optionally but not limited to a cylindrical table, can be movably set on the test machine tool 7 by screws, bolts, etc.

[0026] like Figure 1 、 2 As shown, the bearing assembly 2 is arranged on the support seat 1 and is used to install at least one working condition simulation device; specifically, the top of the bearing assembly 2 may be, but is not limited to, a first threaded interface; the end of the working condition simulation device may be, but is not limited to, a second threaded interface adapted to the first threaded interface, so that the working condition simulation device can be movably arranged above the bearing assembly 2. Those skilled in the art can selectively use which working condition simulation device according to the current simulated working condition. Preferably, the bearing assembly 2 may also optionally, but is not limited to, include a telescopic tube to lift the working condition simulation device, and then lift the object to be detected placed therein, for easy detection. The above-mentioned first threaded interface is preferably arranged at the top of the telescopic tube for quick connection to the working condition simulation device. This threaded connection method has high connection stability and can quickly connect the working condition simulation device, thereby improving detection efficiency.

[0027] The working condition simulation device is used to place the object to be detected and simulate at least one specific working condition of the object to be detected when in use.

[0028] Applying the technical solution of this embodiment, which includes a support base 1, a bearing assembly 2, and at least one working condition simulation device, when it is necessary to perform a performance test on an object to be tested, the support base 1 and bearing assembly 2 can first be installed on the test position 706 of the test machine 7. Then, based on the working condition to be simulated, such as compression or bending, a suitable working condition simulation device can be selected and installed on the bearing assembly 2. Subsequently, the object to be tested, placed in the selected working condition simulation device, can be subjected to a predetermined working condition simulation such as compression or bending. At this point, the test machine 7 can be controlled to perform a performance test on the object to be tested, that is, the actual performance of the object under compression and bending can be tested, so that the test results of its performance indicators, such as compressibility, bendability, conductivity, service life, etc., are more closely aligned with its usage conditions and more in line with actual applications.

[0029] The advantage of this embodiment is that the auxiliary device for performance testing of the present invention can be used to simulate the specific working conditions of the object to be tested in the use state, and then the performance test of the object to be tested in this state can be carried out with the help of the test machine 7 to obtain the detection performance in this state. The result is more accurate and more in line with reality, and it can be used to judge whether the object to be tested meets the actual application requirements. In addition, the overall structure of the device is simple, the operation logic is clear, and it is easy for the user to operate. Preferably, through the threaded interface, different working condition simulation devices can be easily and quickly replaced, and simulation tests under different working conditions can be achieved. The operation is simple and convenient. When purchasing or using the auxiliary device, the operator can adaptably select one or more working condition simulation devices according to the parts and materials to be tested, so as to balance the equipment cost and ease of use.

[0030] like Figure 3-Figure 5 As shown, two preferred embodiments of the working condition simulation device of the present invention are given, which optionally but not limited to include a compression simulation module and / or a bending simulation module for simulating the compression state or bending state of the object to be detected when in use.

[0031] like Figure 3 、 4 As shown, the compression simulation module may optionally include but is not limited to: a lifting component 3, a rotating force arm 4 and a compression simulation component 5; specifically, as Figure 4As shown, the compression simulation component 5 may optionally include, but is not limited to, a trapezoidal groove 501, a T-bar 502, a movable clamp 503, and a first connecting threaded rod 506. The compression simulation component 5 is provided with a trapezoidal groove 501 inside, and a T-bar 502 is provided on the inner bottom surface of the trapezoidal groove 501, which penetrates the bottom surface of the compression simulation component 5. The T-bar 502 can move relative to the trapezoidal groove 501. Two movable clamps 503 are provided inside the trapezoidal groove 501 and above the T-bar 502. The outer sides of the movable clamps 503 match the inner sides of the trapezoidal groove 501. The bottom of the compression simulation component 5 is provided with a first connecting threaded rod 506. The trapezoidal groove 501 is used to accommodate other parts and objects to be detected; the T-bar 502 supports the movable clamps 503 and adjusts the spacing between the movable clamps 503; the movable clamps 503 are used to contact the object to be detected; and the first connecting threaded rod 506 is used to connect to the bearing component 2.

[0032] The advantage of this embodiment is that the spacing between the movable clamping blocks 503 is adjusted by utilizing the inner side of the trapezoidal groove 501 and the relative height of the T-bar 502 and the trapezoidal groove 501, thereby achieving compression of the object to be inspected. The specific working principle is described in Example 1.

[0033] like Figure 4 As shown, preferably, the compression simulation component 5 includes an outer groove 504 and a stopper 505. The outer grooves 504 are provided on both sides of the front end surface of the trapezoidal groove 501, and the stopper 505 is provided on the upper end of the outer groove 504. The outer groove 504 is used to install the stopper 505; the stopper 505 is used to prevent the movable clamp 503 from sliding out of the trapezoidal groove 501.

[0034] The advantage of this embodiment is that the outer groove 504 and the limiting block 505 are provided to limit the moving path of the movable clamping block 503, thereby preventing it from sliding out of the trapezoidal groove 501 and improving the stability of the device.

[0035] like Figure 3 As shown, preferably, the compression simulation component 5 further includes a stabilizing tension spring 507 , and a stabilizing tension spring 507 is provided between one end of the movable clamping block 503 close to the limit block 505 and the outer groove 504 . The stabilizing tension spring 507 is used to stabilize the movable clamping block 503 .

[0036] The advantage of this embodiment is that, by providing the stabilizing tension spring 507 , the movable clamping block 503 is prevented from excessively shaking during the movement process, thereby preventing the object to be inspected from being damaged and affecting the final inspection result.

[0037] like Figure 5As shown, the bending simulation module 6 includes a crossbar 601, a second connecting threaded rod 602, an L-shaped bending rod 603, and a lower pressure piece 705 mounted on the testing machine 7. The second connecting threaded rod 602 is mounted at the bottom of the crossbar 601, and two L-shaped bending rods 603 are symmetrically mounted at the top of the crossbar 601. The crossbar 601 is used to connect the L-shaped bending rods 603; the second connecting threaded rod 602 is used to connect to the threaded telescopic tube; and the L-shaped bending rods 603 are used to bend the object to be tested under the action of the lower pressure piece 705.

[0038] The advantage of this embodiment is that the L-shaped bending rod 603 and the pressing member 705 can be used to bend the object to be detected, thereby realizing detection of the object to be detected in the bent state. In addition, the device has a simple structure, clear operation logic, and is easy for users to operate.

[0039] Example 1

[0040] When in use, first install the support base 1 and the bearing assembly 2 on the test position 706 of the test machine 7 in sequence, and then select a suitable working condition simulation device according to the working condition required to be tested of the object to be tested.

[0041] If it is necessary to test the object to be tested in a compressed state, select the compression simulation module, and then install the lifting component 3, the rotating force arm 4 and the compression simulation component 5 on the upper end of the supporting component 2 in sequence, and then place the object to be tested above the T-bar 502 and between the two movable clamps 503, and then operate the rotating force arm 4 to control the lifting component 3 to make the compression simulation component 5 move downward. At this time, the relative height of the T-bar 502 in the trapezoidal groove 501 rises, thereby reducing the distance between the two movable clamps 503 to achieve compression of the object to be tested. When the compression of the object to be tested reaches the predetermined compression condition, operate the drive track 702 on the test machine 7 so that the object to be tested is located in the high and low temperature control box, and then the parts or materials in the compressed state can be tested.

[0042] If it is necessary to test the object to be tested in a bent state, select the bending simulation module, then install the bending simulation module 6 on the upper end of the supporting component 2, then place the object to be tested across the two L-shaped bending rods 603, and then operate the lower pressure piece 705 in the testing machine 7 to apply external force to the part of the object to be tested between the two L-shaped bending rods 603 to achieve bending deformation of the object to be tested, and then continue to operate the driving track 702 on the testing machine 7 so that the object to be tested is located in the high and low temperature control box 703, and then the parts or materials in the bent state can be tested.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
